Latest company news about Excavator jack hammer most complete maintenance points

As we all know, any active connection parts are easily damaged when the excavator jack hammer is used, but these damages can be avoided as long as they are used and operated correctly.


Let’s see how to use it correctly:


  1. It is necessary to read the operation manual of the crusher before use, prevent unnecessary losses in advance, prevent damage to the excavator jack hammer and excavator, and operate them correctly and efficiently.


  1. Before operation, it is necessary to check whether the bolts and connectors are loose, and at the same time, check whether there is any leakage in the hydraulic pipeline.


  1. Do not use the excavator jack hammer to hit the drill hole on the hard rock.


  1. Do not operate the crusher when the piston rod of the hydraulic cylinder is fully extended or fully retracted.


  1. If the hydraulic hose vibrates violently during use, it is necessary to stop the action of the breaker and check the pressure of the accumulator.


  1. Do not let the crusher work in water.


  1. Do not use the excavator jack hammer to lift heavy objects.


  1. Do not operate the breaker on the tire side of the excavator.


  1. When the excavator jack hammer is installed and connected with other engineering construction machinery, the working pressure and flow rate of the main engine hydraulic system must meet the technical parameters of the hydraulic breaker.


  1. The most suitable hydraulic oil temperature is 50-60 degrees when the crusher is working. If it exceeds 80 degrees, it is necessary to reduce the load of the hydraulic breaker in time.


  1. New and repaired excavator jack hammer must be refilled with nitrogen when they are used, and the pressure is as required by the instructions.


  1. The gap between the shank of the drill rod and the guide sleeve of the cylinder must be lubricated with calcium-based grease or complex calcium-based grease, and it must be filled once per shift.


  1. When the hydraulic breaker is working, the chisel rod must be pressed against the rock first, and a certain pressure must be maintained before the breaker is started.


  1. The excavator jack hammer cannot be used as a crowbar, as there is a risk of breaking the drill rod.


  1. Breaking hammers and fiber rods should be perpendicular to the working surface when in use, and try not to generate radial force.


  1. When the object to be crushed has cracked or started to crack, the impact of the crusher should be stopped immediately to avoid harmful “empty strike”.


  1. Storing the excavator jack hammer: If it is stored for a long time, it is necessary to exhaust the nitrogen and seal the oil inlet and outlet. Note, do not store at high temperature and in an environment below -20 degrees.
